Embodiment Construction
[0010] The base 1 is fixedly connected with the motor base 2, the motor bracket 4, the rotary cylinder 13 and the gap adjustment head limit seat 15, the bottom of the motor body 3 is placed on the motor base 2, and the upper flange is placed on the motor bracket 4. The bottom of the mold 6 is placed on the motor bracket 4 and above the motor flange, the rotor 8 is connected to the output shaft of the motor, the stator 7 is placed between the mold 6 and the rotor 8, and there is an adjustment gap between the mold 6 and the stator 7. One side of the mold 6 is equipped with a spring self-adjusting rod device 5, and the other side is equipped with an error eliminating rod 9 and a gap adjusting rod 11. The error eliminating rod 9 is inserted into the gap adjusting rod 11, and there is a spring 14 between the two. The locking screw 10 is connected with the gap between the mold 6, the bottom is threadedly connected with the gap adjustment rod 11, and the bottom is connected with the e...

The invention, which belongs to the field of manufacturing en electronic vacuum pump for en electric vehicle, relates to a clearance adjusting mechanism for a stator and a rotor of an electric vacuum pump. A motor base, a motor bracket, a rotary cylinder and a clearance adjusting head limiting base are fixedly connected to a base. The bottom of a motor main body is arranged on the motor base; an upper flange is arranged on the motor bracket; and the bottom of a mould is arranged on the motor bracket. A rotor is connected with a motor output shaft; a stator is arranged between the mould and the rotor; and an adjusting clearance is formed between the mould and the stator. A spring self-adjusting rod device is installed at one side of the mould and an error removing lever and a clearance adjusting lever are installed at the other side of the mould. The top of the rotary cylinder is in rotating connection with a clearance adjusting head having a tapered head part. The clearance adjusting mechanism has the following advantages: the structure is novel; the taper of the clearance adjusting head is used for measurement, so that the assembling processes of the stator and the rotor are simplified substantially; the operation is simple and convenient; the clearance can be adjusted; the consistency is high; the product quality is guaranteed; and the production take time is increased.
Description
technical field [0001] The invention belongs to the field of electronic vacuum pump manufacturing for electric vehicles, and is a tool for assembling a stator and a rotor on an electronic vacuum pump assembly line. Background technique [0002] At present, during the stator and rotor assembly process on the electronic vacuum pump assembly line, a mold is fixed on the main body of the vacuum pump. The mold needs to be fixed manually with three M3 screws, and then the stator and rotor are put into the mold and assembled. Finally, the gap between the stator and the rotor is adjusted with ratchet adjustment levers on both sides of the mold, and the size of the gap is measured with a feeler gauge. The whole process is cumbersome and affects the production cycle, which is a bottleneck of the production line. Contents of the invention [0003] The invention provides a stator-rotor gap adjustment mechanism of an electric vacuum pump to solve the problems of cumbersome adjustment o...
